Standards and legal requirements

Winter sports enthusiasts are looking forward to lots of snow. But masses of snow can also lead to unpleasant consequences during weather changes or snow melting. Vehicles can be damaged or people may be injured when snow slides off roofs. This may lead to legal consequences for house owners because in various building regulations of the countries measures are required in order to prevent slipping of the snow masses off roofs.

Various snow retention systems are available for this purpose. For the first time the professional planning and execution of those systems has now been defined in a separate standard. The ÖNORM B3418 published in July 2010 applies to all inclined or curved roofs with a slope of up to 60 degrees.

For the static design of snow retention systems, the load is to be determined in accordance with the standards DIN or ÖNORM EN1991-1-3 and the corresponding national annexes. It is dependent on the location of the object (sea level, snow load zone) and the pitch of the roof.

With REES snow retention systems, you meet the requirements of this standard.
We would be pleased to provide you with information on the retention forces required by this standard.

TÜV certified snow retention systems

The production of our snow retention products is supervised by TÜV Süd. At regular intervals, we check the confirmed properties of our products on a modern test facility, which has been approved by TÜV Süd. This is confirmed by the TÜV test mark, with which the predefined holding forces of our snow retention brackets are confirmed.

Remarks

Despite the fact that the snow retention systems are professionally designed, however, as is expressly stated in ÖNORM 3418, snow can slide off in exceptional circumstances (for example, in the event of snow drifts, unfavourable snow layers). Then the house owner is required to promptly remove the dangerous snow masses.
